Bubbles

Gah!!

I didn't change anything and THIS started happening. There aren't any leaks in the line or anything.

Could it be the impeller?

Big bubbles . Not micro bubbles from the sump.

Is air getting into the return line from a bad fitting?

The pump sucking in air from somewhere? Skimmer pumping out bubbles?

no..

i figured it out..
oddly it has been running for YEARS without this issue, however for some reason the antisyphon hole has now decided that it is too big.

No big deal.. I'll just replace part of the return where it enters the tank and be good to go.

With all the algae that grows on mine, I don't think that I've had the problem. That reminds me, I should clean mine out for when power goes out.
